If you have an existing PBX (private branch exchange) or also known as your phone system, you likely understand its functionality and the specifications it requires to successfully manage your company’s telecommunications. It’s when you seek adding new features or capabilities to an existing PBX that key questions arise. One topic AVOXI frequently hears about is the process of adding a VoIP number to an existing PBX. There are several factors that determine the process, but with our 16+ years of experience with virtual numbers, AVOXI responds to these questions all the time. In this article, we discuss how to add a virtual number to an existing PBX system. This addresses a VoIP solution for you and your telecommunications provider and provides a guide on the approach.
To add a VoIP phone number to your existing PBX, you need to first understand the type of PBX you have and its compatibility with virtual phone numbers. Typically there are three types of in-house PBXs.
- Analog PBX: Older models likely have an analog connection, this means it’s connected to the POTS (plain old telephone service) through copper wires. As technology evolves, this type is slowly becoming obsolete.
- IP / Digital PBX: A digital PBX system, also known as an IP PBX, accepts digital signals and decodes them, relaying messages to a virtual endpoint. Generally, these are 100% web based.
- Hybrid PBX: A hybrid system is a mix between analog and digital. As hybrids they accept both signals.
Depending on your PBX, there are different ways to connect a VoIP number to the system. If you have a digital or hybrid PBX, those offer the easiest, fastest and most affordable option. These are already configured for digital signals. That means that all that needs to be done is VoIP configuration to route calls to the IP address of your PBX.
If you have an older PBX that only receives analog signals, you require hardware to convert the digital signal to analog. This hardware, commonly known as a VoIP gateway, collocates with your PBX. That conversion ensures that the signal between your VoIP phone number and your PBX are compatible.
Adding a VoIP Number to an Existing PBX
After you’ve determined your type of PBX and the steps required to take to make it compatible with digital signals, you need to work directly with your provider to set up your virtual phone number. These virtual numbers or VoIP phone numbers come in different varieties: international toll free numbers, DID local numbers or even UIFN (universal international free phone) numbers. The restrictions, capabilities, and pricing for these numbers is contingent on factors ranging from provider offerings to the originating country to where the calls terminate. Working directly with your provider about adding a VoIP number to an existing PBX helps you understand your VoIP telephone number needs and how those numbers work with your current PBX infrastructure.
